Abstract

Disclosed are a wire rod and a manufacturing method therefor. The wire rod comprises in percentage by weight: 0.02 to 0.15% of C; 0.05 to 0.3% of Si; 0.5 to 1.2% of Mn; 0.3 to 0.9% of Cr; 0.02% or less of P; 0.02% or less of S; 0.01 to 0.05% of sol.Al; 0.01% or less of N; Fe as the remainder; and unavoidable impurities, wherein the wire rod satisfies following formulas 1 and 2, wherein, when the hardness of the wire rod measured in 1/2d position and in 1/4d position in the diameter direction of the wire rod is Hv,1/2d(Hv) and Hv,1/4d(Hv), respectively (here, d is the diameter of the wire). [Formula 1] (Hv,1/2d+Hv,1/4d)/2 = 150 [Formula 2] Hv,1/2d/Hv,1/4d = 1.2.
